               2.2 Revolving Loans.

                      (a) Subject to the terms of paragraph (b) below, the
Lender shall, upon the request of a Borrower from time to time, make Revolving
Loans to such Borrower; provided that at no time may the aggregate amount of
Revolving Loans exceed the Aggregate Availability (with the Aggregate
Availability determined for this purpose as if the amount of the Revolving Loans
were zero). The commitment of the Lender to make Inventory Loans or Equipment
Loans shall terminate upon a Permitted Sale.

                      (b) At no time may the aggregate amount of: (i) A/R Loans
of a Borrower exceed: (x) in the case of CMI, the CMI Availability or (y) in the
case of EFData, the EFData Availability; and provided further that the aggregate
principal amount of A/R Loans advanced against Eligible Permitted Accounts of a
Borrower may at no time exceed the Eligible Permitted Accounts Limit applicable
to such Borrower; (ii) Inventory Loans of a Borrower exceed the Inventory Loans
Limit applicable to such Borrower; or (iii) Equipment Loans of a Borrower exceed
the Equipment Loans Limit applicable to such Borrower. The Lender shall be under
no obligation to make any Equipment Loan to a Borrower if, as at the date such
Loan is to be made, the net book value of the Equipment of the Borrowers as
disclosed in the most-recent balance sheet delivered pursuant to Section 8.2(c)
is less than $35,000,000. The Lender, in its discretion, may elect to exceed an
Availability Limit on one or more occasions, but if it does so, the Lender shall
not be deemed thereby to have changed any such limit or to be obligated to
exceed such limit on any other occasion. If the unpaid balance of the Revolving
Loans exceeds the Aggregate Availability (with Aggregate Availability determined
for this purpose as if the amount of the Revolving Loans were zero), then the
Lender may refuse to make or otherwise restrict Revolving Loans on such terms as
the Lender determines until such excess has been eliminated.

                      (c) The Borrowers, to the extent required or permitted by
Sections 2.2(d) and (e) below, may request Revolving Loans either telephonically
or in writing. Each oral request for a Revolving Loan shall be conclusively
presumed to be made by a person authorized by the relevant Borrower to do so and
the crediting of a Revolving Loan to such Borrower's deposit account, or
transmittal to such Person as such Borrower shall direct, shall conclusively
establish the obligation of the Borrowers to repay such Revolving Loan as
provided herein. If, and to the extent, at the time the requested Revolving Loan
is to be made there is insufficient CMI Availability or EFData Availability (as
applicable) to permit the Revolving Loan to be made as an A/R Loan, such
Revolving Loan shall be made as an Inventory Loan, provided that if, at such
time, the CMI Inventory Limit or EFData Inventory Limit (as applicable) would be
exceeded such Revolving Loan shall, subject to applicable Equipment Loan Limits,
be made as an Equipment Loan. If at any time after an Equipment Loan or
Inventory Loan is made, CMI Availability or EFData Availability (as applicable)
shall become available, then to the extent of such availability the Equipment
Loans or, if there are no Equipment Loans, Inventory Loans outstanding shall be
deemed converted into A/R Loans. If at any time while A/R Loans are outstanding
the CMI Availability or EFData Availability (as applicable) shall be reduced
below the outstanding amount of such A/R Loans, such A/R Loans shall be deemed,
subject to applicable Inventory Loans Limits or Equipment Loans Limits, to be
converted into Inventory Loans or Equipment Loans (as appropriate). The Lender
will charge all Revolving Loans and other Obligations to a loan account of the
Borrowers maintained with the



                                       25.

Lender. All fees, commissions, costs, expenses, and other charges under or
pursuant to the Loan Documents, and all payments made and out-of-pocket expenses
incurred by the Lender pursuant to the Loan Documents, will be charged as
Revolving Loans to the relevant Borrower's loan account as of the date due from
such Borrower or the date paid or incurred by the Lender, as the case may be.

                      (d) Procedure for Borrowing.

                             (i) Each Borrowing of Revolving Loans shall be made
        upon a Borrower's irrevocable written notice ("Notice of Borrowing")
        delivered to the Lender which notice must be received by the Lender (A)
        not later than 11:00 a.m. (Los Angeles, California time) three Business
        Days prior to the requested Funding Date, in the case of LIBOR Rate
        Loans, and (B) no later than 10:00 a.m. (Los Angeles, California time)
        on the requested Funding Date, in the case of Reference Rate Loans,
        specifying:

                             (ii) the amount of the Borrowing;

                             (iii) the requested Funding Date, which shall be a
        Business Day;

                             (iv) in the case of A/R Loans, whether the
        Revolving Loans requested are to be Reference Rate Loans or LIBOR Rate
        Loans;

                             (v) the duration of the Interest Period if the
        requested Revolving Loans are to be LIBOR Rate Loans. If the Notice of
        Borrowing fails to specify the duration of the Interest Period for any
        Borrowing comprised of LIBOR Rate Loans, such Interest Period shall be
        three months; provided, however, that with respect to the Borrowings to
        be made on the Closing Date, such Borrowings will consist of Reference
        Rate Loans only; and

                             (vi) which Borrower will make the Borrowing.

                             (vii) after giving effect to any Borrowing, the
        Borrowers collectively may not have more than three different Interest
        Periods in effect.

                             (viii) with respect to any request for Reference
        Rate Loans, in lieu of delivering the above-described Notice of
        Borrowing a Borrower may give the Lender telephonic notice of such
        request by the required time, with such telephonic notice to be
        confirmed in writing within 24 hours of the giving of such notice but
        Lender shall be entitled to rely on the telephonic notice in making such
        Revolving Loans.

               2.3 Letters of Credit.

                      (a) Subject to the terms and conditions of this Agreement,
the Lender shall, upon a Borrower's request from time to time, cause merchandise
or standby letters of credit to be issued for such Borrower's account (such
letters of credit the "Letters of Credit"). Letters of Credit shall be issued
through an issuer acceptable, in its sole discretion, to and nominated by the



                                       26.

Lender. The Lender will not be required to cause to be issued any Letter of
Credit if: (i) the maximum face amount of the requested Letter of Credit, plus
the aggregate undrawn face amount of all outstanding Letters of Credit and
maximum exposure under outstanding Belgian Guaranties, would exceed $20,000,000;
(ii) the maximum face amount of the requested Letter of Credit and all
commissions, fees, and charges due from the Borrowers to Lender in connection
with the issuance thereof would cause the Borrowings to exceed the Aggregate
Availability or (iii) the expiration date of the Letter of Credit would exceed
the Stated Termination Date or any renewal term or be greater than thirty (30)
months from the date of issuance. All payments made and expenses incurred by the
Lender pursuant to or in connection with Letters of Credit will be charged to
the loan account of the Borrower requesting the relevant Letter of Credit as
Revolving Loans.

                      (b) Other Conditions. In addition to being subject to the
satisfaction of the applicable conditions precedent contained in Section 11, the
obligation of the Lender to cause to be issued any Letter of Credit is subject
to the following conditions precedent having been satisfied in a manner
satisfactory to the Lender:

                             (i) The relevant Borrower requesting issuance of
        the Letter of Credit shall have delivered to the proposed issuer of such
        Letter of Credit, at such times and in such manner as such proposed
        issuer may prescribe, an application in form and substance satisfactory
        to such proposed issuer and the Lender for the issuance of the Letter of
        Credit and such other documents as may be required pursuant to the terms
        thereof, and the form and terms of the proposed Letter of Credit shall
        be satisfactory to the Lender and such proposed issuer; and

                             (ii) As of the date of issuance, no order of any
        court, arbitrator or Public Authority shall purport by its terms to
        enjoin or restrain money center banks generally from issuing letters of
        credit of the type and in the amount of the proposed Letter of Credit,
        and no law, rule or regulation applicable to money center banks
        generally and no request or directive (whether or not having the force
        of law) from any Public Authority with jurisdiction over money center
        banks generally shall prohibit, or request that the proposed issuer of
        such Letter of Credit refrain from, the issuance of letters of credit
        generally or the issuance of such Letters of Credit.

               (c) Issuance of Letters of Credit.

                             (i) Request for Issuance. The Borrower requesting
        issuance of a Letter of Credit shall give the Lender four (4) Business
        Days' prior written notice of such Borrower's request for the issuance
        of a Letter of Credit. Such notice shall be irrevocable and shall
        specify the original face amount of the Letter of Credit requested, the
        effective date (which date shall be a Business Day) of issuance of such
        requested Letter of Credit, whether such Letter of Credit may be drawn
        in a single or in partial draws, the date on which such requested Letter
        of Credit is to expire (which date shall be a Business Day), the purpose
        for which such Letter of Credit is to be issued, and the beneficiary of
        the requested Letter of Credit. The relevant Borrower shall attach to
        such notice the proposed form of the Letter of Credit that the Lender is
        requested to cause to be issued.

                             (ii) No Extensions or Amendment. The Lender shall
        not be obligated to cause any Letter of Credit to be extended or amended

        Letter of Credit immediately when due, irrespective of any claim,

                             (ii) Revolving Loans to Satisfy Reimbursement
        Obligations. In the event that the issuer of any Letter of Credit honors
        a draw under such Letter of Credit and the Borrowers shall not have
        repaid such amount to the issuer of such Letter of Credit pursuant to
        Section 2.3(d)(i), the Lender shall pay the issuer and such amount when
        paid shall constitute a Revolving Loan which shall be deemed to have
        been requested by the Borrower originally requesting the relevant Letter
        of Credit.

               (e) Compensation for Letters of Credit.

                             (i) Letter of Credit Fee. The Borrowers jointly and

        issuer for letters of credit issued by it, including, without
        limitation, its standard fees for issuing, administering, amending,
        renewing, paying and canceling letters of credit and all other fees

        beyond the control of the Lender, including, without limitation, any act
        or omission, whether rightful or wrongful, of any present or future de
        jure or de facto Public Authority. None of the foregoing shall affect,
        impair or prevent the vesting of any rights or powers of the Lender
        under this Section 2.3.

                             (iii) Exoneration. In furtherance and extension,

        in the absence of gross negligence or willful misconduct, shall not put
        the Lender under any resulting liability to either Borrower or relieve
        either Borrower of any of its obligations hereunder to any such Person.

                             (iv) Power of Attorney. In connection with all
        Inventory financed by Letters of Credit, each Borrower hereby appoints
        the Lender, or the Lender's designee, as its attorney, with full power
        and authority: (A) to sign and/or endorse such Borrower's name upon any
        warehouse or other receipts; (B) to sign such Borrower's name on bills
        of lading and other negotiable and non-negotiable documents; (C) to
        clear Inventory through customs in the Lender's or such Borrower's name,
        and to sign and deliver to customs officials powers of attorney in such
        Borrower's name for such purpose; (D) to complete in such Borrower's or
        the Lender's name, any order, sale, or transaction, obtain the necessary
        documents in connection therewith, and collect the proceeds thereof; and
        (E) to do such other acts and things as are necessary in order to enable
        the Lender to obtain possession of the Inventory and to obtain payment
        of the Obligations. Neither the Lender nor its designee, as such
        Borrower's attorney, will be liable for any acts or omissions, nor for
        any error of judgement or mistakes of fact or law. These powers, being
        coupled with an interest, are irrevocable until all Obligations have
        been paid and satisfied.

                             (v) Account Party. The Borrowers hereby each
        authorize and direct any issuer of a Letter of Credit to name such
        Borrower as the "Account Party" in any Letter of Credit requested by
        such Borrower and to deliver to the Lender all instruments, documents
        and other writings and property received by the issuer pursuant to a
        Letter of Credit, and to accept and rely upon the Lender's instructions
        and agreements with respect to all matters arising in connection with a
        Letter of Credit or the application therefor.

                             (vi) Control of Inventory. In connection with all
        Inventory financed by Letters of Credit, the Borrowers will, at the
        Lender's request, instruct all suppliers, carriers, forwarders,
        warehouses or others receiving or holding cash, checks, Inventory,
        documents or instruments in which the Lender holds a security interest
        to deliver them to the Lender and/or subject to the Lender's order, and
        if they shall come into a Borrower's possession, to deliver them, upon
        request, to the Lender in their original form. Each Borrower shall also,
        at the Lender's request, designate the Lender as the consignee on all
        bills of lading and other negotiable and non-negotiable documents.

                      (g) Supporting Letter of Credit; Cash Collateral. If,
notwithstanding the provisions of this Section 2.3 and Section 14 any Letter of
Credit is outstanding upon the termination of this Agreement, then upon such
termination the Borrowers shall deposit with the Lender, at its discretion, with
respect to each Letter of Credit then outstanding, either (i) a standby letter
of credit (a "Supporting Letter of Credit") in form and substance satisfactory
to the Lender, issued by an issuer satisfactory to the Lender in an amount equal
to the greatest amount for which such Letter of Credit may be drawn, under which
Supporting Letter of Credit the Lender is entitled to draw amounts necessary to
reimburse the Lender for payments made by the Lender under such Letter of Credit
or under any credit support or enhancement provided through the Lender with
respect thereto, or (ii) cash in amounts necessary to reimburse the Lender for
payments made by the Lender under such Letter of Credit or under any credit
support or enhancement provided through the Lender. Such Supporting Letter of
Credit or deposit of cash shall be held by the Lender, as security for, and to
provide for the payment of, the aggregate undrawn amount of such Letters of
Credit remaining outstanding.

                      (h) Existing Letters of Credit. On and after the Closing
Date the Existing Letters of Credit shall be deemed for all purposes (including
determination of Aggregate Availability and fees to be collected pursuant to
Section 3.6 and the reimbursement of costs and expenses) to be Letters of Credit
outstanding under this Agreement and shall be governed by and subject to the
application of this Agreement and the other Loan Documents.

               2.4 Belgian Guaranties.

                      (a) On the terms and conditions set forth herein the
Lender shall, upon CMI's request from time to time, cause Belgian Guaranties to
be issued by the Bank for the account of CMI; provided, that the Lender shall
not be obliged to cause the Bank to issue any Belgian Guaranty if: (i) the date
for issue of the relevant Belgian Guaranty is not a Business Day, (ii) as of the
date of its issue the maximum exposure under the requested Belgian Guaranty
(together with all fees, charges, commissions and expenses in connection
therewith) (A) exceeds the Aggregate 



                                       30.

<PAGE>   36

Belgian Guaranty Amount or (B) when aggregated with the undrawn amount of all
outstanding Letters of Credit and the maximum exposure under outstanding Belgian
Guaranties would exceed $20,000,000, (iii) the aggregate amount of Borrowings of
the Borrowers advanced against Eligible Permitted Accounts would exceed the
Eligible Permitted Accounts Subfacility Amount, and (iv) such requested Belgian
Guaranty relates to a contract with the Belgian Beneficiary whose terms have not
been approved by the Lender.

                      (b) The Lender is under no obligation to cause the Bank to
execute and deliver any Belgian Guaranty if: (i) any order, judgment or decree
of any court arbitrator or Public Authority shall by its terms purport to enjoin
or restrain the Lender and/or Bank from executing and delivering such Belgian
Guaranty, or any law, rule or regulation applicable to the Lender and/or the
Bank or any request or directive (whether or not having the force of law) from
any Public Authority with jurisdiction over the Lender and/or the Bank shall
prohibit, or request that the Lender and/or the Bank refrain from, the execution
and delivery of guaranties generally or such Belgian Guaranty in particular or
shall impose upon the Lender and/or the Bank with respect to such Belgian
Guaranty any restriction, reserve or capital requirement (for which the Lender
and/or the Bank is not otherwise compensated hereunder), or shall impose upon
the Lender and/or the Bank any unreimbursed loss, cost or expense; or (ii) the
Bank has received written notice from the Lender or CMI, on or prior to the
Business Day prior to the requested date of issue of such Belgian Guaranty, that
one or more of the applicable conditions contained in Article 11 is not then
satisfied; or (iii) the issue of a Belgian Guaranty shall violate any applicable
policies of the Bank; or (iv) any requested Belgian Guaranty is not otherwise in
form and substance acceptable to the Lender or the Bank.

                      (c) Issuance of Belgian Guaranties. CMI shall give Lender
and the Bank at least four (4) Business Days (or such shorter period as the
Lender and Bank may agree) prior written notice of CMI's request for the
issuance of a Belgian Guaranty. Such notice shall be irrevocable and shall
specify the amount of the Belgian Guaranty requested, the date of issue of the
Belgian Guaranty, the type and nature of Belgian Guaranty requested and such
other information as the Lender or Bank may require.

                      (d) Payments Pursuant to Belgian Guaranties.

                             (i) Payment of Belgian Guaranty Obligations. The
Borrowers jointly and severally undertake to reimburse the Bank the Dollar
Equivalent of any payment under a Belgian Guaranty and other amounts payable
under or in connection with the Belgian Guaranties immediately upon demand,
irrespective of any claim, setoff, defense or other right which the Borrowers
may have at any time against the Bank, the beneficiary of the relevant Belgian
Guaranty or any other Person.

                             (ii) Revolving Loans to Satisfy Reimbursement
Obligations. In the event that the Bank honors a request for payment by a
beneficiary under a Belgian Guaranty and the Borrowers shall not have reimbursed
the Bank pursuant to Section 2.4(d)(i), the Lender shall pay the Bank the Dollar
Equivalent of such amount due and such payment shall constitute a Revolving
Loan, which shall be deemed to be a Reference Rate Loan requested by CMI.

<PAGE>   37

                      (e) Existing Belgian Guaranties. On and after the Closing
Date, the Existing Belgian Guaranties shall be deemed for all purposes to be
Belgian Guaranties outstanding under this Agreement and shall be governed by and
subject to the application of this Agreement and the other Loan Documents.

                      (f) Role of the Bank.

                             (i) The Lender and each Borrower agree that, in
making any payment under a Belgian Guaranty, the Lender and the Bank shall not
have any responsibility to obtain any document or to ascertain or inquire as to
the validity or accuracy of any such document or the authority of the Person
executing or delivery any such document.

                             (ii) The Lender and the Bank shall not be liable:
(A) in respect of the Bank, for any action taken or omitted in connection
herewith at the request of the Lender; (B) for any action taken or omitted in
the absence of gross negligence or willful misconduct; or (C) for the due
execution, effectiveness, validity or enforceability of any document related to
a Belgian Guaranty.

               2.5 ACH Transactions and FX Transactions. Either Borrower may
request and the Lender may, in its sole and absolute discretion, arrange for
either Borrower to obtain from the Bank ACH Transactions and FX Transactions.
The Borrowers agree to indemnify and hold the Lender harmless from all losses,
liabilities, costs, expenses and claims incurred by the Lender arising from or
related to such ACH Transactions and FX Transactions pursuant to the indemnity
referred to in clause (c) below. The Borrowers agree to pay to the Bank all
amounts owing to the Bank pursuant to ACH Transactions and FX Transactions. In
the event that the Borrowers shall not have paid to the Bank such amounts, the
Lender shall pay the Bank and such amounts when paid by the Lender shall
constitute a Revolving Loan requested by the Borrowers. The Borrowers
acknowledge and agree that the obtaining of ACH Transactions and FX Transactions
from the Bank (a) is in the sole and absolute discretion of the Bank, (b) is
subject to all rules and regulations of the Bank, and (c) is due to the Bank
relying on the indemnity of the Lender to the Bank with respect to all risks of
loss associated with the ACH Transactions and FX Transactions.

        3.     INTEREST AND OTHER CHARGES.

               3.1 Interest.

               (a) All Obligations shall bear interest on the unpaid principal
amount thereof from the date made until paid in full in cash at a rate
determined by reference to the Reference Rate or the LIBOR Rate and Sections 3.1
(a)(i) or (ii), as applicable, but not to exceed the Maximum Rate. Subject to
the provisions of Section 3.2, A/R Loans may be converted into, or continued as,
Reference Rate Loans or LIBOR Rate Loans in the manner provided in Section 3.2.
Inventory Loans and Equipment Loans may only be maintained as Reference Rate
Loans. If at any time A/R Loans are outstanding with respect to which notice has
not been delivered to Lender in accordance with the terms of this Agreement
specifying the basis for determining the interest rate applicable thereto, then
those A/R Loans shall be Reference Rate Loans and shall bear interest at a



                                       32.

<PAGE>   38
rate determined by reference to the Reference Rate until notice to the contrary
has been given to the Lender and such notice has become effective. Except as
otherwise provided herein, the Obligations shall bear interest at: (i) a
fluctuating rate per annum equal to the Reference Rate plus the Reference Rate
Margin (as set forth below) for Obligations other than LIBOR Rate Loans,
Inventory Loans or Equipment Loans and (ii) at a rate per annum equal to the
LIBOR Rate plus the LIBOR Margin (as set forth below) for Obligations
constituting LIBOR Rate Loans and (iii) at a fluctuating rate per annum equal to
the Reference Rate plus the Inventory/Equipment Margin (as set forth below) for
Obligations constituting Inventory Loans or Equipment Loans. The initial
Reference Rate Margin, Inventory/Equipment Margin and LIBOR Margin for the six
month period following the Closing Date shall be 0.50%, 1.00% and 2.50%,
respectively. Thereafter the Reference Rate Margin, the Inventory/ Equipment
Margin and the LIBOR Margin shall be determined based upon the aggregate average
daily amount of Borrowings outstanding during the month preceding the borrowing
of the relevant Revolving Loan in accordance with the table set forth below:

</TABLE>

        Each change in the Reference Rate shall be reflected in the interest
rate described above as of the effective date of such change. All interest
charges shall be computed on the basis of a year of three hundred sixty (360)
days and actual days elapsed. All interest shall be payable to Lender on the
first day of each month hereafter.

                      (b) If any Event of Default occurs, then, from the date
such Event of Default occurs until it is cured, or if not cured until all
Obligations are paid and performed in full, the Borrowers, upon demand of
Lender, will pay interest on the unpaid principal balances of the Revolving
Loans at a per annum rate 2% greater than the rate of interest otherwise
specified herein, and the applicable Letter of Credit Fee and Belgian Guaranty
Fee shall be increased by 2%.

                      (c) Unused Line Fee. For every month during the term of
this Agreement, the Borrowers shall pay the Lender a fee (the "Unused Line Fee")
in an amount equal to 0.25% per annum, multiplied by the average daily amount by
which the Maximum Revolving Credit Line exceeds the sum of (i) the average daily
outstanding amount of Revolving Loans during such month, (ii) the average daily
undrawn face amount of all outstanding Letters of Credit during such month, and
(iii) the Aggregate Belgian Guaranty Amount with the outstanding amount of
Revolving Loans calculated for this purpose by applying payments immediately
upon receipt. Such a fee, if any, shall be calculated on the basis of a year of
three hundred sixty (360) days and actual days elapsed, and shall be payable to
the Lender on the first day of each month and on the termination of this
Agreement, in each case, with respect to the prior month or portion thereof.

               3.2 Conversion and Continuation Elections.

                      (a) Each Borrower may, with respect to any Borrowing of
A/R Loans made by such Borrower, upon irrevocable written notice to the Lender
in accordance with Subsection 3.2(b):

                             (i) elect, as of any Business Day, in the case of
        A/R Loans which are Reference Rate Loans, to convert any such Loans (or
        any part thereof in an amount not less than $2,000,000, or that is in an
        integral multiple of $1,000,000 in excess thereof) into LIBOR Rate
        Loans; or

                             (ii) elect, as of the last day of the applicable
        Interest Period, to continue any A/R Loans which are LIBOR Rate Loans
        having Interest Periods expiring on such day (or any part thereof in an
        amount not less than $2,000,000, or that is in an integral multiple of
        $1,000,000 in excess thereof);

provided, that if at any time the aggregate amount of LIBOR Rate Loans in
respect of any Borrowing is reduced, by payment, prepayment, or conversion of
part thereof to be less than $1,000,000, such LIBOR Rate Loans shall
automatically convert into Reference Rate Loans, and on and after such date the
right of the Borrowers to continue such Loans as, and convert such Loans into,
LIBOR Rate Loans, as the case may be, shall terminate.

                      (b) The relevant Borrower shall deliver a notice of
conversion or continuation ("Notice of Conversion/Continuation") to be received
by the Lender (A) not later than 11:00 a.m.(Los Angeles, California time) at
least three (3) Business Days in advance of the date of conversion or
continuation, if the Loans are to be converted into or continued as LIBOR Rate
Loans and (B) not later than 10:00 a.m. (Los Angeles, California time) on the
date of conversion or continuation if the A/R Loans are to be converted into or
continued as Reference Rate Loans and specifying:

                             (i) the proposed Conversion/Continuation Date;

                             (ii) the aggregate amount of A/R Loans to be
        converted or continued;

                             (iii) the type of A/R Loans resulting from the
        proposed conversion or continuation;

                             (iv) the Borrower in respect of whom such Borrowing
        was made.

                      (c) If upon the expiration of any Interest Period
applicable to LIBOR Rate Loans, the relevant Borrower has failed to select
timely a new Interest Period to be applicable to LIBOR Rate Loans or if any
Event or Event of Default then exists, the relevant Borrower shall be deemed to
have elected to convert such LIBOR Rate Loans into Reference Rate Loans
effective as of the expiration date of such Interest Period.



                                       34.

<PAGE>   40

                      (d) During the existence of a Event or Event of Default,
the Borrowers may not elect to have a Loan converted into or continued as a
LIBOR Rate Loan.

                      (e) After giving effect to any conversion or continuation
of Loans, there may not be more than three different Interest Periods in effect
for the Borrowers collectively.

               3.3 Maximum Interest Rate. In no event shall any interest rate
provided for hereunder exceed the maximum rate permissible for corporate
borrowers under applicable law for loans of the type provided for hereunder (the
"Maximum Rate"). If, in any month, any interest rate, absent such limitation,
would have exceeded the Maximum Rate, then the interest rate for that month
shall be the Maximum Rate, and, if in future months, that interest rate would
otherwise be less than the Maximum Rate, then that interest rate shall remain at
the Maximum Rate until such time as the amount of interest paid hereunder equals
the amount of interest which would have been paid if the same had not been
limited by the Maximum Rate. In the event that, upon payment in full of the
Obligations, the total amount of interest paid or accrued under the terms of
this Agreement is less than the total amount of interest which would, but for
this Section 3.3, have been paid or accrued if the interest rates otherwise set
forth in this Agreement had at all times been in effect, then the Borrowers
shall, to the extent permitted by applicable law, pay the Lender, an amount
equal to the excess of (a) the lesser of (i) the amount of interest which would
have been charged if the Maximum Rate had, at all times, been in effect or (ii)
the amount of interest which would have accrued had the interest rates otherwise
set forth in this Agreement, at all times, been in effect over (b) the amount of
interest actually paid or accrued under this Agreement. In the event that a
court determines that the Lender has received interest and other charges
hereunder in excess of the Maximum Rate, such excess shall be deemed received on
account of, and shall automatically be applied to reduce, the Obligations other
than interest, in the inverse order of maturity, and if there are no Obligations
outstanding, the Lender shall refund to the Borrowers such excess.

               3.4 Facility Fee. The Borrowers will pay the Lender on the
Closing Date a facility fee in the amount of $150,000 (the "Facility Fee"). The
Lender and the Borrowers agree that the Facility Fee shall be financed by the
Lender as a Revolving Loan.

               3.5 Collateral Management Fee. The Borrowers will pay the Lender
an annual fee (the "Collateral Management Fee") on the Closing Date and each
anniversary thereafter prior to the termination of this Agreement, in the amount
of $25,000 for each year or portion thereof.

               3.6 Letter of Credit Fee. The Borrowers agree to pay to the
Lender a fee (the "Letter of Credit Fee") equal to the rate per annum equal to
the Letter of Credit Fee Percentage of the undrawn face amount of each Letter of
Credit issued for either Borrowers' account at either Borrowers' request, plus
all out-of-pocket costs, fees and expenses incurred by the Lender in connection
with the application for, issuance of, or amendment to any Letter of Credit,
which costs, fees and expenses could include a "fronting fee" required to be
paid by the Lender to such issuer for the assumption of the settlement risk in
connection with the issuance of such Letter of Credit. The initial Letter of
Credit Fee Percentage applicable during the six month period following the
Closing Date shall be 1.50%. Thereafter the applicable Letter of Credit Fee
Percentage shall be determined 



                                       35.

based upon the aggregate average daily amount of Borrowings outstanding during
the month preceding the date of payment in accordance with the table set forth

</TABLE>


        To the extent, at any time, a Letter of Credit if being issued would be
treated for the purposes of the Availability Limits pursuant to Section 2.3(a)
as being advanced against the Inventory Loan Limit or Equipment Loan Limit of a
Borrower, the Letter of Credit fee applicable to such portion of such Letter of
Credit shall be increased by 0.50%.

        The Letter of Credit Fee shall be payable monthly in arrears on the
first day of each month following any month in which a Letter of Credit was
issued and/or in which a Letter of Credit remains outstanding. The Letter of
Credit Fee shall be computed on the basis of a 360- day year for the actual
number of days elapsed.

               3.7 Belgian Guaranty Fee and Dollar Equivalent Amounts.

                      (a) During the term of this Agreement, the Borrowers agree
to pay to the Lender a fee (the "Belgian Guaranty Fee"), payable on the first
day of each month, equal to the product of (i) the Belgian Guaranty Fee
Percentage multiplied by the maximum exposure under outstanding Belgian
Guaranties (as determined by the Lender in its sole discretion) plus (ii) all
out-of-pocket costs, fees and expenses of the Lender and the Bank in connection
with the application for, issuance of, or amendment to any Belgian Guaranty,
which costs, fees and expenses could include a "fronting fee" required to be
paid by the Lender to the Bank in connection with the issuance of such Belgian
Guaranty.

                      (b) The Belgian Guaranty Fee shall be payable monthly in
advance on the first day of each month hereafter; provided that the first
payment on account of the Belgian Guaranty Fee shall be payable on the Closing
Date in respect of the period from the Closing Date to the first day of the
month following the Closing Date. Such fee shall be calculated on the basis of a
year of three hundred and sixty (360) days and the actual days elapsed.

                      (c) The Lender may, from time to time in its sole
discretion, determine the Dollar Equivalent amount of Belgian Guaranty
Obligations, proposed Belgian Guaranties and the Aggregate Belgian Guaranty
Amount. Absent manifest error, any such determination by the Lender shall be
conclusive and binding on the Borrowers. Subject to Section 6.3, if the Lender
shall have determined that, due to a change in applicable rates of exchange
between Dollars and Belgian Francs, (A) the aggregate principal amount of all
Revolving Loans and outstanding Letters of Credit exceeds the Aggregate
Availability or (B) the Belgian Guaranty Obligations exceeds the Aggregate

                                       36.

<PAGE>   42


Belgian Guaranty Amount, then the Lender shall give notice to CMI which states
the Dollar Equivalent amount of any such excess and requires the Borrowers to
cash collateralize or to make mandatory prepayments so as to eliminate such
excess.

        4. PAYMENTS.

               4.1 Repayments. The Borrowers shall repay the outstanding
principal balance of the Revolving Loans, plus all accrued but unpaid interest
thereon, upon the termination of this Agreement for any reason. In addition, and
without limiting the generality of the foregoing, the Borrowers shall pay to the
Lender, on demand, (a) the amount by which the unpaid principal balance of the
Revolving Loans at any time exceeds the Aggregate Availability at such time
(determined for this purpose as if the amount of the Revolving Loans were zero)
and (b) the amount by which the aggregate amount of any Borrowings exceeds any
other applicable Availability Limit. Upon any Permitted Sale the Borrowers shall
immediately repay any Inventory Loans or Equipment Loans then outstanding.

               4.2 Place and Form of Payments; Extension of Time. All payments
of principal, interest, premium, and other sums due to the Lender shall be made
at the Lender's address set forth in Section 15.11. Except for Proceeds received
directly by the Lender, all such payments shall be made in Dollars in
immediately available funds. If any payment of principal, interest, premium, or
other sum to be made hereunder becomes due and payable on a day other than a
Business Day, the due date of such payment shall be extended to the next
succeeding Business Day and interest thereon shall be payable at the applicable
interest rate during such extension.

               4.3 Application and Reversal of Payments. The Lender shall
determine in its sole discretion the order and manner in which Proceeds of
Collateral and other payments that the Lender receives are applied to any type
of Revolving Loan, interest thereon, and any other Obligations, and the
Borrowers hereby irrevocably waive the right to direct the application of any
payment or Proceeds. The Lender shall have the continuing and exclusive right to
apply and reverse and reapply any and all such Proceeds and payments to any
portion of the Obligations.

               4.4 INDEMNITY FOR RETURNED PAYMENTS. IF AFTER RECEIPT OF ANY
PAYMENT WHICH IS APPLIED TO THE PAYMENT OF ALL OR ANY PART OF THE OBLIGATIONS,
THE LENDER IS FOR ANY REASON COMPELLED TO SURRENDER SUCH PAYMENT TO ANY PERSON
BECAUSE SUCH PAYMENT IS INVALIDATED, DECLARED FRAUDULENT, SET ASIDE, DETERMINED
TO BE VOID OR VOIDABLE AS A PREFERENCE, IMPERMISSIBLE SETOFF, OR A DIVERSION OF
TRUST FUNDS, OR FOR ANY OTHER REASON, THEN: THE OBLIGATIONS OR PART THEREOF
INTENDED TO BE SATISFIED SHALL BE REVIVED AND CONTINUE AND THIS AGREEMENT SHALL
CONTINUE IN FULL FORCE AS IF SUCH PAYMENT HAD NOT BEEN RECEIVED BY THE LENDER
AND THE BORROWERS SHALL BE LIABLE TO PAY TO THE LENDER AND HEREBY DO INDEMNIFY
THE LENDER AND HOLD THE LENDER HARMLESS FOR THE AMOUNT OF SUCH PAYMENT
SURRENDERED. The provisions of this Section 4.4 shall be and remain effective
notwithstanding any contrary action which may have been taken by the Lender in
reliance upon such payment, and any such contrary 



                                       37.

<PAGE>   43

action so taken shall be without prejudice to the Lender's rights under this
Agreement and shall be deemed to have been conditioned upon such payment having
become final and irrevocable. The provisions of this Section 4.4 shall survive
the termination of this Agreement.

        5. LENDER'S BOOKS AND RECORDS; MONTHLY STATEMENTS. The Borrowers agree
that the Lender's books and records showing the Obligations and the transactions
pursuant to this Agreement and the other Loan Documents shall be admissible in
any action or proceeding arising therefrom, and shall constitute prima facie
proof thereof, irrespective of whether any Obligation is also evidenced by a
promissory note or other instrument. The Lender will provide to Borrowers a
monthly statement of Loans, payments, and other transactions pursuant to this
Agreement. Such statement shall be deemed correct, accurate, and binding on the
Borrowers and as an account stated (except for reversals and reapplications of
payments made as provided in Section 4.3 and corrections of errors discovered by
the Lender), unless the Borrowers notify the Lender in writing to the contrary
within thirty (30) days after such statement is rendered. In the event a timely
written notice of objections is given by the Borrowers only the items to which
exception is expressly made will be considered to be disputed by the Borrowers.

        6. TAXES, YIELD PROTECTION AND ILLEGALITY.

               6.1 Taxes.

                      (a) Any and all payments by the Borrowers to the Lender
under this Agreement and any other Loan Document shall be made free and clear
of, and without deduction or withholding for any Taxes. In addition, the
Borrowers shall pay all Other Taxes.

                      (b) The Borrowers agree to indemnify and hold harmless the
Lender for the full amount of Taxes or Other Taxes (including any Taxes or Other
Taxes imposed by any jurisdiction on amounts payable under this Section) paid by
the Lender and any liability (including penalties, interest, additions to tax
and expenses) arising therefrom or with respect thereto, whether or not such
Taxes or Other Taxes were correctly or legally asserted. Payment under this
indemnification shall be made within 30 days after the date the Lender makes
written demand therefor.

                      (c) If the Borrowers shall be required by law to deduct or
withhold any Taxes or Other Taxes from or in respect of any sum payable
hereunder to Lender, then:

                             (i) the sum payable shall be increased as necessary
        so that after making all required deductions and withholdings (including
        deductions and withholdings applicable to additional sums payable under
        this Section) the Lender receives an amount equal to the sum it would
        have received had no such deductions or withholdings been made;

                             (ii) the relevant Borrower shall make such
        deductions and withholdings;



                                       38.

<PAGE>   44

                             (iii) the relevant Borrower shall pay the full
        amount deducted or withheld to the relevant taxing authority or other
        authority in accordance with applicable law; and

                             (iv) the relevant Borrower shall also pay to the
        Lender at the time interest is paid, all additional amounts which the
        Lender specifies as necessary to preserve the after-tax yield the Lender
        would have received if such Taxes or Other Taxes had not been imposed.

               (d) Within 30 days after the date of any payment by a Borrower of
Taxes or Other Taxes, such Borrower shall furnish the Lender the original or a
certified copy of a receipt evidencing payment thereof, or other evidence of
payment satisfactory to the Lender.

               6.2 Illegality.

                      (a) If the Lender determines that the introduction of any
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Public Authority has asserted that
it is unlawful, for the Lender or its applicable lending office to make LIBOR
Rate Loans, then, on notice thereof by the Lender to the Borrowers, any
obligation of the Lender to make LIBOR Rate Loans shall be suspended until the
Lender notifies the Borrowers that the circumstances giving rise to such
determination no longer exist.

                      (b) If the Lender determines that it is unlawful to
maintain any LIBOR Rate Loan, each Borrower shall, upon its receipt of notice of
such fact and demand from the Lender, prepay in full such LIBOR Rate Loans then
outstanding to it, together with interest accrued thereon and amounts required
under Section 6.4, either on the last day of the Interest Period thereof, if the
Lender may lawfully continue to maintain such LIBOR Rate Loans to such day, or
immediately, if the Lender may not lawfully continue to maintain such LIBOR Rate
Loan. If the Borrowers are required to so prepay any LIBOR Rate Loan, then
concurrently with such prepayment, the Borrowers shall borrow from the Lender,
in the amount of such repayment, a Reference Rate Loan.

               6.3 Increased Costs and Reduction of Return.

                      (a) If the Lender determines that, due to either (i) the
introduction of or any change in the interpretation of any law or regulation or
(ii) the compliance by the Lender with any guideline or request from any central
bank or other Public Authority (whether or not having the force of law), there
shall be any increase in the cost to the Lender of agreeing to make or making,
funding or maintaining any LIBOR Rate Loans, then the Borrowers shall be liable
for, and shall from time to time, upon demand, pay to the Lender, additional
amounts as are sufficient to compensate the Lender for such increased costs.

                      (b) If the Lender shall have determined that (i) the
introduction of any Capital Adequacy Regulation, (ii) any change in any Capital
Adequacy Regulation, (iii) any change in the interpretation or administration of
any Capital Adequacy Regulation by any central bank or 



                                       39.

<PAGE>   45

other Public Authority charged with the interpretation or administration
thereof, or (iv) compliance by the Lender or any corporation controlling the
Lender with any Capital Adequacy Regulation, affects or would affect the amount
of capital, reserves, or special deposits required or expected to be maintained
by the Lender or any corporation controlling the Lender and (taking into
consideration such Lender's or such corporation's policies with respect to
capital adequacy and such Lender's desired return on capital) determines that
the amount of such capital, reserves, or special deposits is increased as a
consequence of its loans, credits or obligations under this Agreement, then,
upon demand of the Lender to the Borrowers, the Borrowers shall pay to the
Lender, from time to time as specified by the Lender, additional amounts
sufficient to compensate the Lender for such increase. Notwithstanding the
foregoing, all such amounts shall be subject to the provisions of Section 3.3.

               6.4 Funding Losses. The Borrowers shall reimburse the Lender and
hold the Lender harmless from any loss or expense which the Lender may sustain
or incur as a consequence of:

                      (a) the failure of a Borrower to make on a timely basis
any payment of principal of any LIBOR Rate Loan;

                      (b) the failure of a Borrower to borrow, continue or
convert a Loan after such Borrower has given (or is deemed to have given) a
Notice of Borrowing or a Notice of Conversion/Continuation;

                      (c) the prepayment or other payment (including after
acceleration thereof) of an LIBOR Rate Loan on a day that is not the last day of
the relevant Interest Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its LIBOR Rate Loans or from fees payable to
terminate the deposits from which such funds were obtained.

               6.5 Inability to Determine Rates. If the Lender determines that
for any reason adequate and reasonable means do not exist for determining the
LIBOR Rate for any requested Interest Period with respect to a proposed LIBOR
Rate Loan, or that the LIBOR Rate for any requested Interest Period with respect
to a proposed LIBOR Rate Loan does not adequately and fairly reflect the cost to
the Lender of funding such Loan, the Lender will promptly so notify the Borrower
requesting the LIBOR Rate Loan. Thereafter, the obligation of the Lender to make
or maintain LIBOR Rate Loans hereunder shall be suspended until the Lender
revokes such notice in writing. Upon receipt of such notice, such Borrower may
revoke any Notice of Borrowing or Notice of Conversion/Continuation then
submitted by it. If such Borrower does not revoke such Notice, the Lender shall
make, convert or continue the Loans, as proposed by such Borrower, in the amount
specified in the applicable notice submitted by such Borrower, but such Loans
shall be made, converted or continued as Reference Rate Loans instead of LIBOR
Rate Loans.

               6.6 Survival. The agreements and obligations of the Borrowers in
this Section 6 shall survive the payment of all other Obligations.

        7. COLLATERAL.

                7.1 Grant of Security Interest.

                      (a) As security for the Obligations, each of the Borrowers
hereby grants to the Lender a continuing security interest in, lien on, and
assignment of all of their respective: (i) Receivables, Inventory, Investment
Property, Proprietary Rights, Equipment and Proceeds thereof, wherever located
and whether now existing or hereafter arising or acquired; (ii) moneys,
securities and other property and the Proceeds thereof, now or hereafter held or
received by, or in transit to, the Lender from or for either Borrower, whether
for safekeeping, pledge, custody, transmission, collection or otherwise,
including, without limitation, all of the Borrowers' deposit accounts, credits,
and balances with the Lender and all claims of the Borrowers against the Lender
at any time existing; (iii) Borrowers' deposit accounts with any financial
institutions with which either Borrower maintains deposits; and (iv) Borrowers'
books, records and other Property relating to or referring to any of the
foregoing, including, without limitation, all books, records, ledger cards, data
processing records, computer software and other property and general intangibles
at any time evidencing or relating to the Receivables, Inventory, Investment
Property, Proprietary Rights, Equipment, Proceeds, and other property referred
to above (all of the foregoing, and all other property of either Borrower in
which the Lender may at any time be granted a Lien, being herein collectively
referred to as the "Collateral"). The Lender shall have all of the rights of a
secured party with respect to the Collateral under the UCC and other applicable
laws.

                      (b) All Obligations shall constitute a single loan secured
by the Collateral. The Lender may, in its sole discretion, (i) exchange, waive,
or release any of the Collateral, (ii) apply Collateral and direct the order or
manner of sale thereof as the Lender may determine, and (iii) settle,
compromise, collect, or otherwise liquidate any Collateral in any manner, all
without affecting the Obligations or the Lender's right to take any other action
with respect to any other Collateral.

               7.2 Perfection and Protection of Security Interest. The
Borrowers shall, at their expense, perform all steps requested by the Lender at
any time to perfect, maintain, protect, and enforce the Security Interest
including, without limitation: (a) executing and recording of the Patent and
Trademark Assignments and executing and filing financing or continuation
statements, and amendments thereof, in form and substance satisfactory to the
Lender; (b) delivering to the Lender the originals of all instruments,
documents, and chattel paper, and all other Collateral of which the Lender
determines it should have physical possession in order to perfect and protect
the Security Interest therein, duly endorsed or assigned to the Lender without
restriction; (c) delivering to the Lender warehouse receipts covering any
portion of the Collateral located in warehouses and for which warehouse receipts
are issued; (d) transferring Inventory to warehouses designated by the Lender;
(e) placing notations on either Borrower's books of account to disclose the
Security Interest; (f) executing and delivering to the Lender a security
agreement relating to the Reversions in form and substance satisfactory to the
Lender; (g) delivering to the Lender all letters of credit on which either
Borrower is named beneficiary; (h) executing and delivering or procuring the
execution and delivery of additional security agreements relating to foreign
assets of the Borrowers and their Subsidiaries or domestic assets not covered by
this Agreement or the then-existing Security Agreements, in form and substance
satisfactory to the Lender; (i) enter, and procure the entry of any 



                                      41.

<PAGE>   47

Securities Intermediary or Commodity Intermediary of either Borrower, into an
agreement with the Lender providing for the operation and "control" (as defined
in Section 8106 of the UCC) of Securities Accounts, Commodity Accounts and
Investment Property of either Borrower; and (j) taking such other steps as are
deemed necessary by the Lender to maintain the Security Interest. To the extent
permitted by applicable law, the Lender may file, without either Borrower's
signature, one or more financing statements disclosing the Security Interest.
The Borrowers agree that a carbon, photographic, photostatic, or other
reproduction of this Agreement or of a financing statement is sufficient as
financing statement. If any Collateral is at any time in the possession or
control of any warehouseman, bailee or either Borrower's agents or processors,
then the Borrowers shall notify the Lender thereof and shall notify such Person
of the Security Interest in such Collateral and, upon the Lender's request, if
an Event of Default has occurred and is continuing, instruct such Person to hold
all such Collateral for the Lender's account subject to the Lender's
instructions. If at any time any Collateral is located on any Premises that are
not owned by the Borrowers, then the Borrowers shall obtain written waivers, in
form and substance satisfactory to the Lender, of all present and future Liens
to which the owner or lessor or any mortgagee of such Premises may be entitled
to assert against the Collateral. The Borrowers shall upon request of Lender
notify the Lender of all Security Accounts and Commodity Accounts of the
Borrowers (from time to time) and their contents and shall identify any Brokers,
Securities Intermediaries or Commodity Intermediaries acting for either
Borrower. The Borrowers shall upon request of Lender notify any such Brokers,
Securities Intermediaries and Commodity Intermediaries of the Lender's security
interest in the Borrowers' Investment Property and of the authority of the
Lender to issue directions and entitlement orders with respect to such Property
and procure that such Persons show on their books that Lender is an entitlement
holder with respect to the Investment Property of the Borrowers. The Borrowers
shall ensure that, except for the Lender, Securities Intermediaries and
Commodity Intermediaries acting for the Borrowers, no Person shall at any time
be given "control" (as defined in Section 8106 of the UCC) over any Investment
Property of the Borrowers. From time to time, the Borrowers shall, upon the
Lender's request, execute and deliver confirmatory written instruments pledging
to the Lender the Collateral, but the Borrowers' failure to do so shall not
affect or limit the Security Interest or the Lender's other rights in and to the
Collateral. So long as this Agreement is in effect and until all Obligations
have been fully satisfied, the Security Interest shall continue in full force
and effect in all Collateral (whether or not deemed eligible for the purpose of
calculating the Aggregate Availability or as the basis for any advance, loan,
extension or credit, or other financial accommodation).

               7.3 Location of Collateral. Each of the Borrowers jointly and
severally represents to the Lender that as of the Closing Date: (a) Schedule 7.3
hereto is a correct and complete list of each Borrower's chief executive office,
the location of their respective books and records, the locations of the
Collateral, and the locations of all of their other places of business, and (b)
Schedule 7.3 correctly identifies any of such facilities and locations that are
not owned by the Borrowers and sets forth the names of the owners and lessors or
sub-lessors of, and, to the best of the Borrowers' knowledge, the holders of any
mortgages on, such facilities and locations. The Borrowers covenant and agree
that they will not maintain any Collateral at any location other than those
listed on Schedule 7.3, and they will not otherwise change or add to any of such
locations, unless they give the Lender at least thirty (30) days prior written
notice thereof and execute any and all financing statements and other documents
that the Lender requests in connection therewith.



                                      42.

<PAGE>   48

                7.4 Title to, Liens on, and Sale and Use of Collateral. The
Borrowers jointly and severally represent and warrant to the Lender that: (a)
all Collateral is and will continue to be owned by the Borrowers or their
Subsidiaries, free and clear of all Liens whatsoever, except for the Security
Interest and other Permitted Liens; (b) neither Borrower has entered into any
agreement with any Person (other than pursuant to this Agreement) providing for
the exercise of direction or control (within the meaning of Section 8106 of the
UCC) over any Investment Property; (c) the Security Interest will not be subject
to any prior Lien except for the Liens described in (c), (e), (h) and (i) of the
definition of Permitted Liens; (d) the Borrowers or their Subsidiaries, owning
Collateral will use, store, and maintain the Collateral with all reasonable care
and will use the Collateral for lawful purposes only; and (e) the Borrowers and
their Subsidiaries will not, without the Lender's prior written approval, sell,
lease, or dispose of or permit the sale or disposition of the Collateral or any
portion thereof, except for sales of Inventory in the ordinary course of
business and as permitted by Section 7.9. The inclusion of Proceeds in the
Collateral shall not be deemed the Lender's consent to any sale or other
disposition of the Collateral except as expressly permitted herein.

                7.5 Appraisals. Whenever an Event or Event of Default exists,
the Borrowers shall, at their expense and upon the Lender's request, provide the
Lender with appraisals or updates thereof of any or all of the Collateral from
an appraiser acceptable to Lender.

                7.6 Access and Examination. The Lender may at all reasonable
times have access to, examine, audit, make extracts from and inspect the
records, files, and books of account of the Borrowers or any of their
Subsidiaries and the Collateral and may discuss the Borrowers' and any of their
Subsidiaries' affairs with the Borrowers' or such Subsidiaries' officers and
management. The Borrowers and their Subsidiaries will deliver to the Lender any
instrument necessary for the Lender to obtain records from any service bureau
maintaining records for a Borrower or any of their Subsidiaries. The Lender may,
at any time when an Event of Default exists and at the Borrowers' expense, make
copies of all of the Borrowers' books and records, or require the Borrowers or
any of their Subsidiaries to deliver such copies to the Lender. The Lender may,
without expense to the Lender, use such of a Borrowers' or any of their
Subsidiaries' personnel, supplies, and Premises as may be reasonably necessary
for maintaining or enforcing the Security Interest. The Lender shall have the
right, at any time, in Lender's name or in the name of a nominee of the Lender,
to verify the validity, amount or any other matter relating to the Accounts of
the Borrowers or their Subsidiaries, by mail, telephone, or otherwise.

                7.7 Insurance. The Borrowers shall insure the Collateral against
loss or damage by fire with extended coverage, theft, burglary, pilferage, loss
in transit, and such other hazards as the Lender shall specify, in amounts,
under policies and by insurers acceptable to the Lender. Borrowers shall also
maintain flood insurance for Inventory and Equipment located in an area
designated as a "flood prone" or a "flood risk area" (hereinafter "SFHA"), as
defined by the Flood Disaster Protection At of 1973, in an amount to be
reasonably determined by the Lender, and shall comply with the additional
requirements of the National Flood Insurance Program as set forth therein. The
Borrowers shall cause the Lender to be named in each insurance policy as secured
party and loss payee or additional insured, in a manner acceptable to the
Lender. Each policy of insurance shall contain a clause or endorsement requiring
the insurer to give not less than thirty (30) days prior written notice to the
Lender in the event of cancellation of the policy for any reason whatsoever and



                                      43.

<PAGE>   49

a clause or endorsement stating that the interest of the Lender shall not be
impaired or invalidated by any act or neglect of the Borrowers or the owner of
any premises where collateral is located nor by the occupation of such premises
for purposes more hazardous than are permitted by such policy. The Borrowers
shall pay all premiums for such insurance when due, and shall deliver to the
Lender certificates of insurance and, if requested, photocopies of the policies.
If the Borrowers fail to pay such fees or to procure such insurance or the
premiums therefor when due, the Lender may (but shall not be required to) do so
and charge the costs thereof to the either Borrower's loan account as a
Revolving Loan. The Borrowers shall promptly notify the Lender of any loss,
damage, or destruction to the Collateral or arising from its use, whether or not
covered by insurance. The Lender is hereby authorized to collect all insurance
proceeds directly. After deducting from such proceeds the expenses, if
any,incurred by Lender in the collection or handling thereof, Lender may apply
such proceeds to the reduction of the Obligations in such order as Lender
determines, or at the Lender's option may permit or require the Borrowers to use
such money, or any part thereof, to replace, repair, restore or rebuild the
Collateral in a diligent and expeditious manner.

                7.8 Collateral Reporting. The Borrowers will provide the Lender
with the following documents, for each of the Borrowers, at the following times
in form satisfactory to the Lender: (a) on a daily basis, a schedule of credit
memos and reports, a schedule of collections of accounts receivable, and a
schedule of Accounts created since the last such schedule; (b) on a daily basis
a detailed list of invoices and remittances for each account; (c) on a monthly
basis, a copy of the final page of both cash and sales journals reconciled to
schedules received on a daily basis; (d) upon request, copies of invoices,
credit memos, shipping and delivery documents; (e) detailed monthly agings of
accounts receivable to be delivered no later than the 10th day of each month
respecting the immediately preceding month; (f) monthly inventory reports by
category (including valuations determined on a valuation method acceptable to
Lender) for all inventory located in the United States in a State in which a
first priority security interest in favor of the Lender has been perfected, to
be delivered by the 20th day of each month with respect to the immediately
preceding month; (g) upon request, monthly perpetual inventory reports; (h)
monthly agings of accounts payable no later than the 10th day of the following
month; (i) upon request, copies of purchase orders, invoices, and delivery
documents for Inventory and Equipment acquired by the Borrowers; (j) copies of
invoices issued against the Belgian Guaranties and copies of the Guarantees
issued; (k) other such reports as to the Collateral as the Lender shall request
from time to time; and (l) certificates of an officer or appropriate approved
employee designated by the chief executive officer, chief financial officer or
treasurer of the relevant Borrower and reasonably acceptable to Lender,
certifying as to the foregoing.

                7.9 Accounts.

                      (a) The Borrowers hereby jointly and severally represent
and warrant to the Lender and agree with the Lender that: (i) each existing
Account represents, and each future Account will represent, a bona fide sale or
lease and delivery of goods by the Borrowers, or rendition of services by the
Borrowers, in the ordinary course of the Borrowers' business; (ii) each existing
Account of the Borrowers is, and each future Account of the Borrowers will be a
valid, binding and enforceable obligation of its relevant Account Debtor for a
liquidated amount payable by the Account Debtor thereon on the terms set forth
in the invoice therefor or in the schedule thereof 



                                      44,

<PAGE>   50

delivered to the Lender, without offset, deduction, defense, or counterclaim;
(iii) no payment will be received with respect to any Account of the Borrowers,
and no credit, discount, or extension, or agreement therefor will be granted on
any Account of the Borrowers, except as reported to the Lender in accordance
with this Agreement; (iv) each copy of an invoice delivered to the Lender by the
Borrowers will be a genuine copy of the original invoice sent to the Account
Debtor named therein; and (v) all goods described in any invoice representing a
sale of goods will have been delivered to the Account Debtor and all services of
the Borrowers described in any invoice will have been performed.

                      (b) The Borrowers shall not re-date any invoice or sale or
make sales on extended dating beyond that customary in the relevant Borrower's
business or extend or modify any Account. If a Borrower becomes aware of any
matter affecting any Account of either Borrower, including information regarding
the Account Debtor's creditworthiness, such Borrower will promptly so advise the
Lender.

                      (c) The Borrowers shall not accept any note or other
instrument (except a check or other instrument for the immediate payment of
money) with respect to any Account (other than an ABN AMRO Receivable) of either
Borrower without the Lender's written consent. If the Lender consents to the
acceptance of any such note or other instrument, it shall be considered as
evidence of the such Account and not payment thereof, and the relevant Borrower
will promptly deliver such note or instrument to the Lender appropriately
endorsed. Regardless of the form of presentment, demand, notice of dishonor,
protest, and notice of protest with respect thereto, the Borrowers will remain
liable thereon until such note or instrument is paid in full.

                      (d) The Borrowers shall notify the Lender promptly of all
disputes and claims with any of their Account Debtors and settle or adjust them
at no expense to the Lender, but no discount, credit or allowance shall be
granted to any such Account Debtor without the Lender's consent, except for
discounts, credits and allowances made or given in the ordinary course of the
relevant Borrower's business when no Event of Default exists hereunder. The
Borrowers shall send the Lender a copy of each credit memoranda in excess of
$25,000 as soon as issued and copies of all credit memorandum on a weekly basis.
The Lender may at all times when an Event of Default exists hereunder settle or
adjust disputes and claims directly with customers or Account Debtors of the
Borrowers for amounts and upon terms which the Lender considers advisable and,
in all cases, the Lender will credit the Borrower's loan accounts with only the
net amounts received by the Lender in payment of any Accounts of the Borrowers.

                      (e) If an Account Debtor of either Borrower returns any
Inventory to a Borrower when no Event of Default exists, then the relevant
Borrower shall promptly determine the reason for such return and shall issue a
credit memorandum to such Account Debtor in the appropriate amount. The
Borrowers shall immediately report to the Lender any return involving an amount
in excess of $25,000 and shall report all returns to the Lender on a weekly
basis. Each such report shall indicate the reasons for the returns and the
locations and condition of the returned Inventory. In the event any Account
Debtor of a Borrower returns Inventory to such Borrower when an Event of Default
exists, such Borrower shall: (i) hold the returned Inventory in trust for the
Lender; (ii) segregate all returned Inventory from all of its other Property;
(iii) dispose of the 



                                      45.

<PAGE>   51

returned Inventory solely according to the Lender's written instructions; and
(iv) not issue any credits or allowances with respect thereto without the
Lender's prior written consent. All returned Inventory shall remain subject to
the Security Interest. Whenever any Inventory is returned, the related Account
of the relevant Borrower shall be deemed ineligible, and Aggregate Availability,
CMI Availability and EFData Availability shall be adjusted accordingly.

                7.10 Collection of Accounts; Payments.

                      (a) Until the Lender notifies the Borrowers to the
contrary, the Borrowers shall make collection of all Accounts (other than ABN
AMRO Receivables) of the Borrowers and other Collateral for the Lender, shall
receive all payments in respect thereto as the Lender's trustee, and shall
immediately deliver all such payments to the Lender in their original form duly
endorsed in blank or deposit them into a Payment Account established at the
Lender's request, as the Lender may direct. If the Lender requests, the
Borrowers shall establish a lock-box service for collections of their Accounts
(other than ABN AMRO Receivables) at a bank mutually acceptable to the Lender
and the Borrowers and pursuant to documentation satisfactory to the Lender. If
such lock-box service is established, the Borrowers shall instruct all their
relevant Account Debtors to make all payments directly to the address
established for such service. If, notwithstanding such instructions, the
Borrowers receive any Proceeds of their Accounts (other than ABN AMRO
Receivables), they shall receive such payments as the Lender's trustee, and
shall immediately deliver such payments to the Lender in their original form
duly endorsed in blank or deposit them into a Payment Account, as the Lender may
direct. All collections received in any such lock box or Payment Account or
directly by the Borrowers or the Lender, and all funds in any Payment Account or
other account to which such collections are deposited, shall be the sole
property of the Lender and subject to the Lender's sole control. The Lender or
the Lender's designee may, at any time after the occurrence of an Event of
Default, notify obligors that the Borrowers' Accounts (other than the ABN AMRO
Receivables) have been assigned to the Lender and of the Security Interest
therein, and may collect them directly and charge the collection costs and
expenses to the Borrowers' loan accounts as a Revolving Loan. At the Lender's
request, the Borrowers shall execute and deliver to the Lender such documents as
the Lender shall require to grant the Lender access to any post office box in
which collections of their Accounts (other than the ABN AMRO Receivables) are
received.

                      (b) If sales of the Borrowers' Inventory are made or
services are rendered for cash, the Borrowers shall immediately deliver to the
Lender the identical checks, cash, or other forms of payment which the Borrowers
receive.

                      (c) All payments received by the Lender on account of
Accounts (other than the ABN AMRO Receivables) or as Proceeds of other
Collateral will be the Lenders' sole property and will be immediately credited
to the Borrowers' loan accounts (conditional upon final collection) to reduce
Obligations. From and after the Closing Date, the Agent shall be entitled to
charge the Borrower interest on all such collections deemed to have been
received on a particular Business Day, in an amount equal to one-half (1/2) of
the amount that would be applicable (at the rates specified in Section 3.1) if
such collections have been in fact received at or before 12:00 (Los Angeles,
California time) on the next succeeding Business Day. This one-half (1/2)
Business Day 



                                      46.

<PAGE>   52

"clearance charge" shall be due and payable irrespective of whether such
collections were provisionally applied to reduce the Obligations.

                      (d) In the event the Borrowers repay all of the
Obligations upon the termination of this Agreement, other than through the
Lender's receipt of payments on account of the Borrowers' Accounts or Proceeds
of other Collateral, such payment will be credited (conditional upon final
collection) to the Borrowers' loan accounts.

                7.11 Inventory. The Borrowers jointly and severally represent
and warrant to the Lender that all of their Inventory is and will be held for
sale or lease, or to be furnished in connection with the rendition of services
in the ordinary course of the Borrowers' business and is and will be fit for
such purposes. The Borrowers will keep their Inventory in good and marketable
condition, at their own expense. The Borrowers will not, without prior written
notice to the Lender, acquire or accept any Inventory on consignment or
approval. The Borrowers agree that all their Inventory will be produced in
accordance with the Federal Fair Labor Standards Act of 1938, as amended, and
all rules, regulations, and orders thereunder. The Borrowers will maintain a
perpetual inventory reporting system at all times. The Borrowers will conduct a
physical count of their Inventory at least once per Fiscal Year, and at such
other times as the Lender requests, and shall promptly, upon completion, supply
the Lender with a copy of such count accompanied by a report of the value of
such Inventory (valued at the lower of cost, on a first-in, first-out basis, or
market value). The Borrowers will not without the Lender's prior written
consent, sell any of their Inventory on a bill-and-hold, guaranteed sale, sale
and return, sale on approval, consignment, or other repurchase or return basis.

                7.12 Equipment. The Borrowers jointly and severally represent
and warrant to the Lender that all of their Equipment is and will be used or
held for use in the Borrowers' businesses and is and will be fit for such
purposes. The Borrowers shall keep and maintain their Equipment in good
operating condition and repair (ordinary wear and tear excepted) and shall make
all necessary replacements thereof. The Borrowers shall promptly inform the
Lender of any material additions to or deletions from their Equipment. The
Borrowers shall not permit any of their Equipment to become a fixture to real
property or an accession to other personal property, unless the Lender has a
valid, perfected, and first priority Security Interest in such real or personal
property. The Borrowers will not, without the Lender's prior written consent,
alter or remove any identifying symbol or number on the Equipment. The Borrowers
shall not, without the Lender's prior written consent, sell, lease as a lessor,
or otherwise dispose of any of the Equipment; provided, however, that the
Borrowers may dispose of Equipment pursuant to a Permitted Sale and the
Borrowers may dispose without the Lender's consent, subject to the conditions
set forth below, of obsolete or unusable Equipment having an orderly liquidation
value no greater than $100,000 individually and $1,000,000 in the aggregate in
any Fiscal Year. In the event any of the Borrowers' Equipment is sold,
transferred or otherwise disposed of with the Lender's prior written consent or
as otherwise permitted hereby and: (a) such sale, transfer or disposition is
effected without replacement of such Equipment, or such Equipment is replaced by
Equipment leased by either Borrower, or by Equipment purchased by either
Borrower subject to a lien or other right constituting a Permitted Lien, then
the relevant Borrower shall deliver all of the cash proceeds of any such sale,
transfer or disposition to the Lender, which proceeds shall be applied to the
repayment of the Obligations; or 



                                      47.

<PAGE>   53

(b) such sale, transfer or disposition is made in connection with the purchase
by either Borrower of replacement Equipment (other than subject to a Permitted
Lien), then the Borrowers shall use the proceeds of such sale, transfer or
disposition to finance the purchase by either Borrower of replacement Equipment
and shall deliver to the Lender written evidence of the use of the proceeds for
such purchase. All replacement Equipment purchased by the Borrowers shall be
free and clear of all liens, claims and encumbrances, except for the Security
Interest and other Permitted Liens.

                7.13 Documents, Instruments, and Chattel Paper. The Borrowers
jointly and severally represent and warrant to the Lender that: (a) all
documents, instruments, and chattel paper describing, evidencing, or
constituting Collateral, and all signatures and endorsements thereon, are and
will be complete, valid, and genuine; and (b) all goods evidenced by such
documents, instruments, and chattel paper are and will be owned by the Borrowers
free and clear of all Liens other than Permitted Liens.

                                                                                
                7.14 Right to Cure. The Lender may, in its sole discretion and
at any time, pay any amount or do any act required of either of the Borrowers
hereunder to preserve, protect, maintain or enforce the Obligations, the
Collateral or the Security Interest, which such Borrower fails to pay or do,
including, without limitation, payment of any judgment against such Borrower,
any insurance premium, any warehouse charge, any finishing or processing charge,
any landlord's claim, and any other Lien upon or with respect to the Collateral.
All payments that the Lender makes under this Section 7.11 and all out-of-pocket
costs and expenses that the Lender pays or incurs in connection with any action
taken by it hereunder shall be charged to the Borrowers' loan account as a
Revolving Loan. Any payment made or other action taken by the Lender under this
Section 7.11 shall be without prejudice to any right to assert an Event of
Default hereunder.

                7.15 Power of Attorney. Each of the Borrowers hereby appoints
the Lender and the Lender's designees as such Borrower's attorney, with power:
(a) to endorse such Borrower's name on any checks, notes, acceptances, money
orders, or other forms of payment or security that come into the Lender's
possession; (b) to sign such Borrower's name on any invoice, bill of lading, or
other document of title relating to any Collateral, on drafts against customers,
on assignments of Accounts, on notices of assignment, financing statements and
other public records, on verifications of Accounts and on notices to Account
Debtors and to file any such financing statements by electronic means with or
without a signature as authorized or required by applicable law or filing
procedure; (c) to notify the post office authorities, when an Event of Default
exists, to change the address for delivery of such Borrower's mail to an address
designated by the Lender and to receive, open and dispose of all mail addressed
to such Borrower; (d) to send requests for verification of Accounts to Account
Debtors; (e) to give directions (including entitlement orders) to any Securities
Intermediary or Commodity Intermediary of the Borrowers, or other Person, as to
the disposition of any Investment Property of the Borrowers and to exercise
dominion and control over any Securities Account and Commodity Account of either
Borrower and to enter into agreements with any Securities Intermediary or
Commodity Intermediary as to the operation and control of such Securities
Accounts or Commodity Accounts; (f) to collect, receive, give receipt for and
otherwise deal with any dividends or other distributions and proceeds resulting
from any Investment Property; and (g) to do all things necessary to carry out
this Agreement. Each of the Borrowers ratifies and 



                                      48.

<PAGE>   54

approves all acts of such attorney. Neither the Lender nor the attorney will be
liable for any acts or omissions or for any error of judgment or mistake of fact
or law. These powers, being coupled with an interest, shall be irrevocable until
this Agreement has been terminated and the Obligations have been fully
satisfied.

                7.16 Lender's Rights, Duties, and Liabilities. The Borrowers
assume all responsibility and liability arising from or relating to the use,
sale, or other disposition of the Collateral. The Obligations shall not be
affected by any failure of the Lender to take any steps to perfect the Security
Interest or to collect or realize upon the Collateral, nor shall loss of or
damage to the Collateral release the Borrowers from any of the Obligations.
Following the occurrence of and continuation of an Event of Default, the Lender
may (but shall not be required to), without notice to or consent from either
Borrower, sue upon or otherwise collect, extend the time for payment of, modify
or amend the terms of, compromise or settle for cash, credit, or otherwise upon
any terms, grant other indulgences, extensions, renewals, compositions, or
releases, and take or omit to take any other action with respect to the
Collateral, any security therefor, any agreement relating thereto, any insurance
applicable thereto, or any Person liable directly or indirectly in connection
with any of the foregoing, without discharging or otherwise affecting the
liability of the Borrowers for the Obligations or under this Agreement or any
other agreement now or hereafter existing between the Lender and the Borrowers.

                7.17 Site Visits, Observations and Testing. The Lender and its
agents and representatives will have the right at any reasonable time to enter
and visit the Premises and any other place where any property of the Borrowers
is located for the purposes of observing the Premises, taking and removing soil
or groundwater samples, and conducting tests on any part of the Premises. The
Lender is under no duty, however, to visit or observe the Premises or to conduct
tests, and any such acts by the Lender will be solely for the purposes of
protecting the Lender's security and preserving the Lender's rights under this
Agreement. No site visit, observation or testing by the Lender will result in a
waiver of any default of the Borrowers or impose any liability on the Lender. In
no event will any site visit, observation or testing by the Lender be a
representation that hazardous substances are or are not present in, on or under
the Premises, or that there has been or will be compliance with any law,
regulation or ordinance pertaining to hazardous substances or any other
applicable governmental law. Neither the Borrowers nor any other party is
entitled to rely on any site visit, observation or testing by the Lender. The
Lender owes no duty of care to protect the Borrowers or any other party against,
or to inform the Borrowers or any other party of, any hazardous substances or
any other adverse condition affecting the Premises. The Lender may in its
discretion disclose to the Borrowers or any other party any report or findings
made as a result of, or in connection with, any site visit, observation or
testing by the Lender. The Borrowers understand and agree that the Lender makes
no warranty or representation to the Borrowers or any other party regarding the
truth, accuracy or completeness of any such report or findings that may be
disclosed. The Borrowers also understand that depending on the results of any
site visit, observation or testing by the Lender and disclosed to the Borrowers,
the Borrowers may have a legal obligation to notify one or more environmental
agencies of the results, that such reporting requirements are site-specific, and
are to be evaluated by the Borrowers without advice or assistance from the
Lender. In each instance, the Lender will give the relevant Borrower reasonable
notice before entering the Premises 



                                      49.

<PAGE>   55

or any other place the Lender is permitted to enter under this Section 7.17. The
Lender will make reasonable efforts to avoid interfering with the Borrower's use
of the Premises or any other property in exercising any rights provided
hereunder.

                7.18 Release of Security Interest in Equipment. Upon a Permitted
Sale, the repayment of all Inventory Loans and Equipment Loans pursuant to
Section 4.1 and the termination of the Lender's commitment to make Inventory
Loans and Equipment Loans pursuant to Section 2.2(a), the Lender agrees, at the
cost and expense of the Borrowers, to release the Security Interest to the
extent, and solely to the extent, that it relates to the Equipment. At the
expense of the Borrowers the Lender agrees to execute and deliver all documents
which the Borrowers may reasonably request to evidence the termination of such
Security Interest in so far as it relates to the Equipment.

        8. BOOKS AND RECORDS; FINANCIAL INFORMATION; NOTICES.

               8.1 Books and Records. The Borrowers shall maintain, at all
times, correct and complete books, records and accounts in which complete,

in accordance with GAAP consistent with those applied in the preparation of the

reflect in such accounts and in all Financial Statements proper liabilities and
reserves for all taxes and proper provision for depreciation and amortization of
Property and bad debts, all in accordance with GAAP. The Borrowers shall
maintain at all times books and records pertaining to the Collateral in such
detail, form, and scope as the Lender shall reasonably require, including
without limitation records of: (a) all payments received and all credits and
extensions granted with respect to the Borrowers' respective Accounts; (b) the
return, rejection, repossession, stoppage in transit, loss, damage, or
destruction of any of the Borrowers' respective Inventory; and (c) all other
dealings affecting the Collateral.

               8.2 Financial Information. The Borrowers shall promptly furnish
to the Lender or its agents all such financial information as the Lender shall

severally and continuously warrant and represent to the Lender, at all times

Documents, to incur the Obligations, and to grant the Security Interest. Each of
the Borrowers has taken all necessary corporate action (including, without

consent, approval, or authorization of, or declaration or filing with, any

with the Borrowers' execution, delivery, and performance of this Agreement and
the other Loan Documents, except for those already duly obtained. This Agreement
and the other Loan Documents have been duly executed and delivered by each of
the Borrowers and constitute the legal, valid and binding obligations of each of
the Borrowers, enforceable against them in accordance with their respective
terms without defense, setoff, or counterclaim. The Borrowers' execution,
delivery, and performance of this Agreement and the other Loan Documents do not
and will not conflict with, or constitute a violation or breach of, or

upon the Property of either Borrower or any of their Subsidiaries (except as

terms of (a) any mortgage, lease, agreement, or instrument to which either
Borrower or any of their Subsidiaries is a party or which is binding upon them,

of incorporation or bylaws of either Borrower or any of their Subsidiaries.

               9.2 Validity and Priority of Security Interest. The provisions of
this Agreement, the Existing Collateral Documents, and the other Loan Documents
create legal and valid Liens on all the Collateral in the Lender's favor, and
when all proper filings, recordings, and other actions necessary to perfect such
Liens have been made or taken, such Liens will constitute perfected and
continuing Liens on all the Collateral, having priority over all other Liens on
the Collateral except for the Permitted Liens identified in Section 7.2 and
enforceable against the Borrowers and all third parties. All representations and
warranties by the Borrowers or any of their Subsidiaries in the Existing
Collateral Documents are true and correct in all material respects on and as of
the date made or deemed made.

herewith, whether required by the UCC or otherwise, shall constitute reasonable
notice to the Borrowers if such notice is mailed by registered or certified
mail, return receipt requested, postage prepaid, or is delivered personally
against receipt, at least five (5) 



                                      70.

days prior to such action to the Borrowers' addresses specified in or pursuant
to Section 15.11. If any Collateral is sold on terms other than payment in full
at the time of sale, no credit shall be given against the Obligations until the
Lender receives payment, and if the buyer defaults in payment, the Lender may
resell the Collateral without further notice to the Borrowers. In the event the
Lender seeks to take possession of all or any portion of the Collateral by
judicial process, each of the Borrowers irrevocably waives: (a) the posting of
any bond, surety or security with respect thereto which might otherwise be
required; (b) any demand for possession prior to the commencement of any suit or
action to recover the Collateral; and (c) any requirement that the Lender retain
possession and not dispose of any Collateral until after trial or final
judgment. The Borrowers recognize that (due to securities laws or otherwise) the
Lender may be unable to make a public sale of Investment Property and expressly
agree that a private sale to a restricted group of persons, for investment
purposes rather than general distribution, shall be considered a commercially
reasonable sale. The Borrowers agree that the Lender has no obligation to
preserve rights to the Collateral or marshal any Collateral for the benefit of
any Person. The Lender is hereby granted a license or other right to use,
without charge, the Borrowers' labels, patents, copyrights, name, trade secrets,
trade names, trademarks, and advertising matter, or any similar property, in
completing production of, advertising or selling any Collateral, and the
Borrowers' rights under all licenses and all franchise agreements shall inure to
the Lender's benefit. The proceeds of sale shall be applied first to all
expenses of sale, including attorney's fees, and second, in whatever order the
Lender elects, to all Obligations. The Lender will return any excess to the
Borrower or such other Person as shall be legally entitled thereto and the
Borrower shall remain liable for any deficiency.

                      (c) If an Event of Default occurs, each of the Borrowers
hereby waives (i) all rights to notice and hearing prior to the exercise by the
Lender of the Lender's rights to repossess the Collateral without judicial
process or to replevy, attach or levy upon the Collateral without notice or
hearing, and (ii) all rights of set-off and counterclaim against Lender.

                      (d) If the Lender terminates this Agreement upon an Event
of Default, the Borrowers shall pay the Lender, immediately upon termination, a
fee equal to the early termination fee that would have been payable under
Section 14 if this Agreement had been terminated on that date pursuant to the
Borrowers' election.

        14. TERM AND TERMINATION. This Agreement shall expire on June 30, 2000
(the "Stated Termination Date") unless earlier terminated or automatically
extended as provided in this Section. This Agreement shall automatically be
renewed on the Stated Termination Date and at the end of any renewal term for
successive one-year terms, unless this Agreement is terminated as provided
below. The Lender and the Borrowers shall have the right to terminate this
Agreement, without premium or penalty, on the Stated Termination Date or at the
end of any renewal term by giving the other written notice not less than sixty
(60) days prior to the end of such term by registered or certified mail. The
Borrowers may also terminate this Agreement at any time prior to the Stated
Termination Date or during any renewal term if: (a) they give the Lender sixty
(60) days prior written notice of termination by registered or certified mail;
(b) they pay and perform all Obligations on or prior to the effective date of
termination; and (c) they pay the Lender, on or prior to the effective date of
termination, and in addition to any other prepayment premium required



                                      71.

hereunder and the fees required by Section 6.4, (i) two percent (2%) of the
average amount of the Revolving Loans, Letters of Credit and Belgian Guaranties
outstanding during the prior 180 day period (or lesser period if within 180 days
of the Closing Date) if such termination is made on or prior to the first
Anniversary Date; and (ii) one percent (1%) of the average amount of the
Revolving Loans, Letters of Credit and Belgian Guaranties outstanding during the
prior 180 day period if such termination is after the first Anniversary Date;
provided that should such termination after the first Anniversary Date result
from a refinancing by the Bank (either as sole lender or as Agent for a
syndicate of Lenders) of the credit facility constituted by this Loan Agreement,
such fee shall be waived. The Lender may also terminate this Agreement without
notice while an Event of Default exists. Upon the effective date of termination
of this Agreement for any reason whatsoever, all Obligations shall become
immediately due and payable and Borrowers shall immediately arrange for the
cancellation as of such termination date of Letters of Credit and Belgian
Guaranties then outstanding. Notwithstanding the termination of this Agreement,
until all Obligations (other than, to the extent that such rights remain
inchoate, the rights of the Lender pursuant to Section 6.6) are paid and
performed in full, the Lender shall retain all its rights and remedies hereunder
(including, without limitation, in all then existing and after-arising
Collateral).

        15. MISCELLANEOUS.

               15.1 Cumulative Remedies; No Prior Recourse to Collateral. The
enumeration herein of the Lender's rights and remedies is not intended to be
exclusive, and such rights and remedies are in addition to and not by way of
limitation of any other rights or remedies that the Lender may have under the
UCC or other applicable law. The Lender shall have the right, in its sole
discretion, to determine which rights and remedies are to be exercised and in
which order. The exercise of one right or remedy shall not preclude the exercise
of any others, all of which shall be cumulative. The Lender may, without
limitation, proceed directly against the Borrowers to collect the Obligations
without any prior recourse to the Collateral.

               15.2 No Implied Waivers. No act, failure or delay by the Lender
shall constitute a waiver of any of its rights and remedies. No single or
partial waiver by the Lender of any provision of this Agreement or any other
Loan Document, or of breach or default hereunder or thereunder, or of any right
or remedy which the Lender may have, shall operate as a waiver of any other
provision, breach, default, right or remedy or of the same provision, breach,
default, right or remedy on a future occasion. No waiver by the Lender shall
affect its rights to require strict performance of this Agreement.

               15.3 Severability. If any provision of this Agreement shall be
prohibited or invalid, under applicable law, it shall be ineffective only to
such extent, without invalidating the remainder of this Agreement.

               15.4 Governing Law. This Agreement shall be deemed to have been
made in the State of California and shall be governed by and interpreted in
accordance with the laws of such state, except that no doctrine of choice of law
shall be used to apply the laws of any other state or jurisdiction.



                                       72.

<PAGE>   78

               15.5 Consent to Jurisdiction and Venue; Service of Process. Each
of the Borrowers agrees that, in addition to any other courts that may have
jurisdiction under applicable laws, any action or proceeding to enforce or
arising out of this Agreement or any of the other Loan Documents may be
commenced in the Courts of the State of California for San Francisco County, or
in the United States District Court for the Northern District of California, and
the Borrowers consent and submit in advance to such jurisdiction and agree that
venue will be proper in such courts on any such matter. Each of the Borrowers
hereby waives personal service of process and agrees that a summons and
complaint commencing an action or proceeding in any such court shall be properly
served and shall confer personal jurisdiction if served by registered or
certified mail to the Borrowers. Should the Borrowers fail to appear or answer
any summons, complaint, process or papers so served within thirty (30) days
after the mailing or other service thereof, it shall be deemed in default and an
order or judgment may be entered against it as demanded or prayed for in such
summons, complaint, process or papers. The choice of forum set forth in this
section shall not be deemed to preclude the enforcement of any judgment obtained
in such forum, or the taking of any action under this Agreement to enforce the
same, in any appropriate jurisdiction.

               15.6 Waiver of Jury Trial. THE BORROWERS EACH HEREBY WAIVE TRIAL
BY JURY, RIGHTS OF SETOFF, AND THE RIGHT TO IMPOSE COUNTERCLAIMS IN ANY
LITIGATION IN ANY COURT WITH RESPECT TO, IN CONNECTION WITH, OR ARISING OUT OF
THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, THE OBLIGATIONS OR THE COLLATERAL, OR
ANY INSTRUMENT OR DOCUMENT DELIVERED PURSUANT HERETO OR THERETO, OR ANY OTHER
CLAIM OR DISPUTE HOWSOEVER ARISING, BETWEEN THE BORROWERS AND THE LENDER. THE
BORROWERS EACH CONFIRM THAT THE FOREGOING WAIVERS ARE INFORMED AND FREELY MADE.

               15.7 Arbitration; Reference Proceeding.

                      (a) ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE PARTIES,
INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR RELATING TO THIS AGREEMENT
OR ANY AGREEMENTS OR INSTRUMENTS RELATING HERETO OR DELIVERED IN CONNECTION
HEREWITH AND ANY CLAIM BASED ON OR ARISING FROM AN ALLEGED TORT, SHALL AT THE
REQUEST OF ANY PARTY BE DETERMINED BY ARBITRATION. THE ARBITRATION SHALL BE
CONDUCTED IN ACCORDANCE WITH THE UNITED STATES ARBITRATION ACT (TITLE 9, U.S.
CODE), NOTWITHSTANDING ANY CHOICE OF LAW PROVISION IN THIS AGREEMENT, AND UNDER
THE COMMERCIAL RULES OF THE AMERICAN ARBITRATION ASSOCIATION ("AAA"). THE
ARBITRATION SHALL BE CONDUCTED WITHIN SAN FRANCISCO COUNTY, CALIFORNIA. THE
ARBITRATOR(S) SHALL GIVE EFFECT TO STATUTES OF LIMITATION IN DETERMINING ANY
CLAIM. ANY CONTROVERSY CONCERNING WHETHER AN ISSUE IS ARBITRABLE SHALL BE
DETERMINED BY THE ARBITRATOR(S). JUDGMENT UPON THE ARBITRATION AWARD MAY BE
ENTERED IN ANY COURT HAVING JURISDICTION. THE INSTITUTION AND 



                                      73.

<PAGE>   79

MAINTENANCE OF AN ACTION FOR JUDICIAL RELIEF OR PURSUIT OF A PROVISIONAL OR
ANCILLARY REMEDY SHALL NOT CONSTITUTE A WAIVER OF THE RIGHT OF ANY PARTY,
INCLUDING THE PLAINTIFF, TO SUBMIT THE CONTROVERSY OR CLAIM TO ARBITRATION IF
ANY OTHER PARTY CONTESTS SUCH ACTION FOR JUDICIAL RELIEF.

                      (b) Notwithstanding the provisions of subparagraph (a), no
controversy or claim shall be submitted to arbitration without the consent of
all parties if, at the time of the proposed submission, such controversy or
claim arises from or relates to an obligation to the Lender which is secured by
real property collateral located in California. If all parties do not consent to
submission of such a controversy or claim to arbitration, the controversy or
claim shall be determined as provided in subparagraph (c).

                      (c) A controversy or claim which is not submitted to
arbitration as provided and limited in subparagraphs (a) and (b) shall, at the
request of any party, be determined by a reference in accordance with California
Code of Civil Procedure Section 638 et seq. If such an election is made, the
parties shall designate to the court a referee or referees selected under the
auspices of the AAA in the same manner as arbitrators are selected in
AAA--sponsored proceedings. The presiding referee of the panel, or the referee
if there is a single referee, shall be an active attorney or retired judge.
Judgment upon the award rendered by such referee or referees shall be entered in
the court in which such proceeding was commenced in accordance with California
Code of Civil Procedure Sections 644 and 645.

                      (d) No provision of this paragraph shall limit the right
of any party to this Agreement to exercise self-help remedies such as setoff, to
foreclose against or sell any real or personal property collateral or security,
or to obtain provisional or ancillary remedies from a court of competent
jurisdiction before, after, or during the pendency of any arbitration or other
proceeding. The exercise of a remedy does not waive the right of either party to
resort to arbitration or reference. At the Lender's option, foreclosure under a
deed of trust or mortgage may be accomplished either by exercise of power of
sale under the deed of trust or mortgage or by judicial foreclosure.

               15.8 Survival of Representations and Warranties. All of the
Borrowers' representations and warranties contained in this Agreement shall
survive the execution, delivery, and acceptance thereof by the parties,
notwithstanding any investigation by the Lender or its agents.

               15.9 Other Security and Guaranties. The Lender may, without
notice or demand and without affecting the Borrowers' obligations hereunder,
from time to time: (a) take from any Person and hold collateral (other than the
Collateral) for the payment of all or any part of the Obligations and exchange,
enforce or release such collateral or any part thereof; and (b) accept and hold
any endorsement or guaranty of payment of all or any part of the Obligations and
release or substitute any such endorser or guarantor, or any Person who has
given any Lien in any other collateral as security for the payment of all or any
part of the Obligations, or any other Person in any way obligated to pay all or
any part of the Obligations.

               15.10 Fees and Expenses. The Borrowers shall pay to the Lender on
demand all costs and expenses that the Lender pays or incurs in connection with
the negotiation, preparation, consummation, administration, enforcement, and
termination of this Agreement and the other Loan Documents, including, without
limitation: (a) attorneys' and paralegals' fees and disbursements of counsel to
the Lender (including, without limitation, a reasonable estimate of the
allocable cost of in-house counsel and staff); (b) costs and expenses including
attorneys' and paralegals' fees and disbursements (including, without
limitation, a reasonable estimate of the allocable cost of in-house counsel and
staff) for any amendment, supplement, waiver, consent, or subsequent closing in
connection with the Loan Documents and the transactions contemplated thereby;
(c) costs and expenses of lien and title searches and title insurance; (d)
Taxes, fees and other charges for recording the mortgages, filing financing
statements and continuations, and other actions to perfect, protect, and
continue the Security Interest; (e) sums paid or incurred to pay any amount or
take any action required of the Borrowers under the Loan Documents that the
Borrowers fail to pay or take; (f) costs of appraisals, inspections, and
verifications of the Collateral, including, without limitation, travel, lodging,
meals, and other expenses together with an allocated charge of $575 per day for
each auditor employed by the Lender for inspections of the Collateral and the
Borrowers' operations; (g) costs and expenses of forwarding loan proceeds,
collecting checks and other items of payment, and establishing and maintaining
Payment Accounts and lock boxes; (h) all amounts that the Borrowers are required
to pay in connection with the Letters of Credit or Belgian Guaranties; (i) costs
and expenses of preserving and protecting the Collateral; and (j) costs and
expenses including attorneys' and paralegals' fees and disbursements (including,
without limitation, a reasonable estimate of the allocable cost of in-house
counsel and staff) paid or incurred to obtain payment of the Obligations,
enforce the Security Interest, sell or otherwise realize upon the Collateral,
and otherwise enforce the provisions of the Loan Documents, or to defend any
claims made or threatened against the Lender arising out of the transactions
contemplated hereby (including without limitation, preparations for and
consultations concerning any such matters). The foregoing shall not be construed
to limit any other provisions of the Loan Documents regarding costs and expenses
to be paid by the Borrowers. All of the foregoing costs and expenses shall be
charged to the Borrowers' loan account as Revolving Loans.

               15.11 Notices.

                      (a) The Borrowers agree that all notices, requests or
other communications (including pursuant to Section 15.5) with respect to the
Borrowers may be made by notice to or from CMI individually whether or not any
copy is also sent to EFData.

                      (b) Except as otherwise provided herein, all notices,
demands, and requests that either party is required or elects to give to the
other shall be in writing, shall be delivered personally against receipt, or
sent by recognized overnight courier services, or mailed by registered or
certified mail, return receipt requested, postage prepaid, and shall be

                      (a) THE BORROWERS HEREBY INDEMNIFY, DEFEND AND HOLD THE
LENDER, AND ITS DIRECTORS, OFFICERS, AGENTS, EMPLOYEES AND COUNSEL, HARMLESS
FROM AND AGAINST ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES, DEFICIENCIES,
JUDGMENTS, PENALTIES OR EXPENSES IMPOSED ON, INCURRED BY OR ASSERTED AGAINST ANY
OF THEM, WHETHER DIRECT, INDIRECT OR CONSEQUENTIAL ARISING OUT OF OR BY REASON
OF ANY LITIGATION, INVESTIGATIONS, CLAIMS, OR PROCEEDINGS (WHETHER BASED ON ANY
FEDERAL, STATE OR LOCAL LAWS OR OTHER STATUTES OR REGULATIONS, INCLUDING,

                                      76.

<PAGE>   82

BASED UPON THE NEGOTIATION, PREPARATION, EXECUTION, DELIVERY, ENFORCEMENT,
PERFORMANCE OR ADMINISTRATION OF THIS AGREEMENT, ANY OTHER LOAN DOCUMENT, OR ANY
UNDERTAKING OR PROCEEDING RELATED TO ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY
OR ANY ACT, OMISSION TO ACT, EVENT OR TRANSACTION RELATED OR ATTENDANT THERETO,
INCLUDING, WITHOUT LIMITATION, AMOUNTS PAID IN SETTLEMENT, COURT COSTS, AND THE
FEES AND EXPENSES OF COUNSEL REASONABLY INCURRED IN CONNECTION WITH ANY SUCH
LITIGATION, INVESTIGATION, CLAIM OR PROCEEDING AND FURTHER INCLUDING, WITHOUT
LIMITATION, ALL LOSSES, DAMAGES (INCLUDING CONSEQUENTIAL DAMAGES), EXPENSES OR
LIABILITIES SUSTAINED BY THE LENDER IN CONNECTION WITH ANY ENVIRONMENTAL
INSPECTION, MONITORING, SAMPLING, OR CLEANUP OF THE ENCUMBERED REAL ESTATE
REQUIRED OR MANDATED BY ANY ENVIRONMENTAL LAW; PROVIDED, HOWEVER, THAT THE
BORROWERS SHALL NOT INDEMNIFY THE LENDER, ITS DIRECTORS, OFFICERS, AGENTS,
EMPLOYEES AND COUNSEL FROM SUCH DAMAGES RESULTING FROM THEIR GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT.

                      (b) The Borrowers hereby indemnify, defend and hold
harmless the Lender from any loss or liability directly or indirectly arising
out of the use, generation, manufacture, production, storage, release,
threatened release, discharge, disposal or presence of a hazardous substance.
This indemnity will apply whether the hazardous substance is on, under or about
the Borrowers' or their Subsidiaries' property or operations or property leased
to the Borrowers or their Subsidiaries. The indemnity includes but is not
limited to attorneys' fees (including the reasonable estimate of the allocated
cost of in-house counsel and staff). The indemnity extends to the Lender, its
parent, subsidiaries and all of their directors, officers, employees, agents,
successors, attorneys and assigns. "Hazardous substances" means any substance,
material or waste that is or becomes designated or regulated as "toxic,"
"hazardous," "pollutant," or "contaminant" or a similar designation or
regulation under any federal, state or local law (whether under common law,
statute, regulation or otherwise) or judicial or administrative interpretation
of such, including without limitation petroleum or natural gas.

                      (c) Without limiting the foregoing, if, by reason of any
suit or proceeding of any kind, nature, or description against the Borrowers, or
by the Borrowers or any other party against the Lender, which in the Lender's
sole discretion makes it advisable for the Lender to seek counsel for protection
and preservation of its liens and security assets, or to defend its own
interest, such expenses and counsel fees shall be allowed to the Lender. To the
extent that the undertaking to indemnify, pay and hold harmless set forth in
this Section 15.12 may be unenforceable because it is violative of any law or
public policy, the Borrowers shall contribute the maximum portion which it is
permitted to pay and satisfy under applicable law, to the payment and
satisfaction of all indemnified matters incurred by the Lender. The indemnity
contained in Section 15.12 shall survive the payment of the Obligations and the
termination of this Agreement. All of the foregoing costs and expenses shall be
part of the Obligations and secured by the Collateral.



                                      77.

<PAGE>   83

               15.13 Waiver of Notices. Unless otherwise expressly provided
herein, the Borrowers waive presentment, protest and notice of demand or
dishonor and protest as to any instrument, as well as any and all other notices
to which it might otherwise be entitled. No notice to or demand on the Borrowers
which the Lender may elect to give shall entitle the Borrowers to any or further
notice or demand in the same, similar or other circumstances.

               15.14 Binding Effect; Assignment. The provisions of this
Agreement shall be binding upon and inure to the benefit of the respective
representatives, successors and assigns of the parties hereto; provided,
however, that no interest herein may be assigned by the Borrowers without the
prior written consent of the Lender. The rights and benefits of the Lender
hereunder shall, if the Lender so agrees, inure to any assignee of the
Obligations or any part thereof.

               15.15 Modification. This Agreement is intended by the Borrowers
and the Lender to be the final, complete, and exclusive expression of the
agreement between them. This Agreement supersedes any and all prior oral or
written agreements relating to the subject matter hereof and may not be
contradicted by evidence of prior, contemporaneous or subsequent oral agreements
of the parties. There are no oral agreements between the parties. No
modification, rescission, waiver, release, or amendment of any provision of this
Agreement shall be made, except by a written agreement signed by the Borrowers
and a duly authorized officer of the Lender (provided that revised schedules may
be substituted for existing schedules to the extent the Lender consents in
writing to any request therefor by the Borrower).

               15.16 Counterparts. This Agreement may be executed in any number
of counterparts, and by the Lender and the Borrowers in separate counterparts,
each of which shall be an original, but all of which shall together constitute
one and the same agreement.

               15.17 Captions. The captions contained in this Agreement are for
convenience only, are without substantive meaning and should not be construed to
modify, enlarge, or restrict any provision.

               15.18 Right of Set-Off. Whenever an Event of Default exists, the
Lender is hereby authorized at any time and from time to time, to the fullest
extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by the Lender or any affiliate of the Lender to
or for the credit or the account of the Borrowers against any and all of the
Obligations, whether or not then due and payable. The Lender agrees promptly to
notify the Borrowers after any such set-off and application made by the Lender,
provided that the failure to give such notice shall not affect the validity of
such set-off and application.

               15.19 Participating Lender's Security Interests. The Lender may,
without notice to or consent by the Borrowers, grant one or more participations
in the Loans to Participating Lenders. If a Participating Lender shall at any
time with the Borrowers' knowledge participate with the Lender in the Loans, the
Borrowers hereby grant to such Participating Lender, and the Lender and such
Participating Lender shall have and are hereby given, a continuing lien on and
security interest in 



                                      78.

<PAGE>   84

any money, securities and other property of the Borrowers in the custody or
possession of the Participating Lender, including the right of setoff, to the
extent of the Participating Lender's participation in the Obligations, and such
Participating Lender shall be deemed to have the same right of setoff to the
extent of Participating Lender's participation in the Obligations under this
Agreement as it would have it were a direct lender.

               15.20 Joint and Several Obligations; Obligations Absolute.

                      (a) Each Borrower hereby agrees that all of the
Obligations set forth herein are the joint and several obligations of the
Borrowers and acknowledges that each Loan to, each Letter of Credit and each
Belgian Guaranty issued for the account of, either Borrower will benefit each of
the Borrowers. Each Borrower hereby further agrees and unconditionally
guarantees to the Lender that the obligations of the other Borrower under this
Agreement, to the extent such obligations are the joint and several obligations
of the Borrowers (such obligations of the other Borrower being referred to
herein, with respect to each Borrower, as the "Other Borrower's Obligations")
will be paid strictly in accordance with the terms of this Agreement, regardless
of any law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of the Lender with respect thereto.
The liability of each Borrower for the Other Borrower's Obligations shall be
absolute and unconditional irrespective of:

                             (i) any lack of validity or enforceability of this
        Agreement, the other Loan Documents or any other agreement or instrument
        relating hereto or thereto;

                             (ii) any change in the time, manner or place of
        payment of, or in any other term of, all or any of the Other Borrower's
        Obligations, or any other amendment or waiver of or any consent to
        departure from this Agreement or the other Loan Documents;

                             (iii) any exchange, release or non-perfection of
        any Collateral, or any release or amendment or waiver of or consent to
        departure from any guaranty, for all or any of the Other Borrower's
        Obligations; or

                             (iv) any other circumstance which might otherwise
        constitute a defense available to, or a discharge of, any Borrower other
        than such Borrower or a guarantor.

Each Borrower's obligations under this Agreement shall continue to be effective
or be reinstated, as the case may be, if at any time any payment of any of the
Other Borrower's Obligations is rescinded or must otherwise be returned by the
Lender upon the insolvency, bankruptcy or reorganization of a Borrower or
otherwise, all as though such payment had not been made.

                      (b) Each Borrower hereby waives, to the extent permitted
by applicable law, with respect to the Other Borrower's Obligations:

                             (i) any requirement that the Lender secure or
        insure any security interest or lien on any property subject thereto or
        exhaust any right or take any action against the other Borrower or any
        other Person or any Collateral;

                             (ii) any defense arising by reason of any claim or
        defense based upon an election of remedies by the Lender (including,
        without limitation, an election to nonjudicially foreclose on any real
        or personal property Collateral) which in any manner impairs, reduces,
        releases or otherwise adversely affects its subrogation, reimbursement
        or contribution rights or other rights to proceed against the other
        Borrower or any other Person or any Collateral;

                             (iii) any defense arising by reason of the failure
        of the other Borrower or any of its Subsidiaries to properly execute any
        Loan Document or otherwise comply with applicable legal formalities;

                             (iv) any defense or benefits that may be derived
        from California Civil Code Section 2808, 2809, 2810, 2819, 2845 or 2850,
        or California Code of Civil Procedure Section 580a, 580d or 726, or
        comparable provisions of the laws of any other jurisdiction and all
        other suretyship defenses it would otherwise have under the laws of
        California or any other jurisdiction. Accordingly, each of the Borrowers
        waives all rights and defenses that such Borrower may have because the
        other Borrower's Obligations are secured by real property. This means,
        among other things: (A) the Lender may collect from a Borrower without
        first foreclosing on any real or personal property Collateral pledged by
        a Borrower; and (B) if the Lender forecloses on any real property
        Collateral pledged by a Borrower: (1) the amount of the debt may be
        reduced only by the price for which that Collateral is sold at the
        foreclosure sale, even if the Collateral is worth more than the sale
        price, and (2) the Lender may collect from a Borrower even if the
        Lender, by foreclosing on the real property Collateral, has destroyed
        any right such Borrower may have to collect from the other Borrower.
        This is an unconditional and irrevocable waiver of any rights and
        defenses the Borrowers may have because the other Borrower's debt is
        secured by real property;

                             (v) any duty on the part of the Lender to disclose
        to such Borrower any matter, fact or thing relating to the business,
        operation or condition of the other Borrower and its respective assets
        now known or hereafter known by the Lender;

                             (vi) all benefits of any statute of limitations
        affecting such Borrower's liability in respect of the Other Borrower's
        Obligations;

=                             (vii)  all setoffs and counterclaims;

                             (viii) promptness, diligence, presentment, demand
        for performance and protest;



                                      80.

<PAGE>   86

                             (ix) notice of nonperformance, default,
        acceleration, protest or dishonor;

                             (x) except for any notice otherwise required by
        applicable laws that may not be effectively waived by such Borrower,
        notice of sale or other disposition of any Collateral; and

                             (xi) notice of the existence, creation, renewal,
        modification, execution or incurring of any Other Borrower's
        Obligations.
